Set the correct path to os-collect-config

os-collect-config is installed in /usr/bin. This adjusts the systemd
service file accordingly to make it work for openSUSE. On Fedora the
wrong path didn't cause any problems because /bin is just a symlink to
/usr/bin there.

Add quotes around $DISTRO

The lsb_release -si output might contain spaces. E.g. on openSUSE it is
"openSUSE project".
